Cost-benefit study confirms benefits of walking and cycling investment

The study shows the benefits of walking and cycling—primarily health gains and carbon emissions reduction—outweighed the costs of better facilities and associated educational campaigns by ten to one.

Few international studies have put an economic value on health and emissions outcomes, and Victoria University’s Associate Professor Ralph Chapman says there has not been a robust economic analysis of the benefits of New Zealand’s Model Communities Programme (MCP) to date. Model Communities are urban environments where walking and cycling are offered to the community as the easiest transport choices. The intention is to deliver safer environments for novice users.

The MCP funded investment in New Plymouth and Hastings in cycle paths, other walking and cycling facilities, cycle parking, ‘shared spaces’, media campaigns and events, such as Share the Road, and cycle-skills training.

Professor Chapman’s study estimated the benefits of health and other outcomes by comparing the two MCP cities—New Plymouth and Hastings—with two similar cities not participating in the MCP.

The research found that the most important economic benefits were health gains from use of active transport. The study estimated that the annual benefits for health were two lives saved plus significant reductions in cardiac disease, diabetes, cancer, and respiratory disease.

“An estimate of the reductions in transport-related carbon emissions showed that the carbon savings are modest compared with the health gains, but are nevertheless valuable as we transition to a low-carbon economy,” says Professor Chapman.
